Hair care advice is often passed down from one generation to another. Maybe you have been told to leave oil on overnight, brush your hair exactly 100 times, rinse with cold water, or avoid washing your hair too often because shampoo causes hair fall.
Some of these habits may feel familiar, but familiar does not always mean effective.
Several popular hair care beliefs can contribute to unnecessary breakage, scalp irritation, product buildup, or poor hair-care habits. Knowing what actually benefits your hair can help you build a simpler and more effective routine.
And while the focus is often on skincare when searching for the best skincare products for beginners, understanding basic hair and scalp care is just as important. Healthy-looking hair starts with taking care of the scalp and treating the hair gently.
Myth 1: Trimming Your Hair Makes It Grow Faster
The myth: Getting regular haircuts makes your hair grow faster from the roots.
The truth: Hair grows from follicles in the scalp, so cutting the ends cannot change the rate at which those follicles produce new hair.
That does not mean trimming is pointless. Removing damaged or split ends can reduce further splitting and breakage, helping you retain more of the length you have already grown.
What to Do Instead
-
Trim your hair when you notice split or damaged ends rather than following a strict schedule
-
Focus on maintaining a healthy scalp
-
Eat a balanced diet and make sure you are getting adequate nutrition
-
Remember that genetics, hormones, health, age, and nutrition can all influence hair growth
A haircut can help your hair look and feel healthier, but it cannot make your roots grow faster.
Myth 2: Washing Your Hair Every Day Causes Hair Fall
The myth: Shampooing every day strips the scalp of its natural oils and directly causes excessive hair loss.
The truth: Washing your hair does not normally cause the follicles to suddenly start shedding. Hair that comes out during shampooing is often hair that was already in the natural shedding stage.
What matters more is whether your washing routine is appropriate for your scalp.
Someone with a very oily scalp may need to wash more frequently, while someone with a dry scalp may be comfortable washing less often.
What to Do Instead
-
Choose your washing frequency according to your scalp's oiliness and needs
-
Wash more frequently if your scalp becomes excessively oily or sweaty
-
Use a gentle shampoo if frequent washing causes dryness or irritation
-
Concentrate shampoo on the scalp rather than repeatedly scrubbing the lengths
-
Apply conditioner mainly through the lengths and ends
There is no universal rule that says everyone should wash their hair a specific number of times per week.
Myth 3: Brushing Your Hair 100 Times a Day Makes It Healthier
The myth: Repeatedly brushing your hair distributes natural oils, stimulates the scalp, and makes hair stronger and shinier.
The truth: Your hair does not need 100 brush strokes a day.
Excessive brushing creates friction and mechanical stress. Over time, this can contribute to cuticle damage, frizz, split ends, and breakage.
Brushing gently to remove tangles and style your hair is enough. More brushing does not automatically mean healthier hair.
What to Do Instead
-
Brush only when necessary
-
Detangle gently, starting from the ends and working upward
-
Use a wide-tooth comb when appropriate, particularly for wet or easily tangled hair
-
Avoid pulling aggressively through knots
-
Choose a brush or comb suited to your hair texture
The goal is gentle detangling, not reaching a magic number of brush strokes.
Myth 4: Leaving Hair Oil Overnight Gives Better Results
The myth: The longer you leave oil on your hair, the more benefits your hair and scalp receive.
The truth: Keeping oil on your hair overnight does not automatically make it more nourishing.
For some people, leaving oil on the scalp for long periods can contribute to buildup or make existing scalp concerns feel worse. This is especially relevant if you already have an oily scalp or are prone to dandruff.
Oiling the hair can help reduce friction and improve the feel of dry lengths, but longer application does not necessarily equal better results.
What to Do Instead
-
Apply a suitable hair oil before washing if you enjoy oiling your hair
-
Give it enough time to coat the hair rather than assuming it needs to stay overnight
-
Concentrate oil on dry lengths and ends if your scalp is prone to buildup
-
Choose an oil based on your hair type and personal preference
-
Wash thoroughly afterward without aggressively scrubbing the scalp
If your scalp becomes itchy, flaky, or irritated after oiling, reconsider whether scalp oiling is right for you.
Myth 5: Cold Water Seals the Cuticle and Makes Hair Grow Faster
The myth: Finishing your shower with cold water closes the hair cuticle, dramatically increases shine, and stimulates hair growth.
The truth: Cold water is not a switch that permanently closes the hair cuticle or activates hair growth.
A cooler rinse may make hair feel smoother for some people, but it does not change the rate at which hair follicles produce new hair.
Hair growth takes place at the follicle within the scalp, so the temperature of the water touching the surface of your hair is not a reliable way to stimulate it.
What to Do Instead
-
Use comfortably warm or lukewarm water when washing your hair
-
Avoid very hot water if it leaves your scalp or hair feeling dry
-
Use conditioner to improve softness and manageability
-
Use a suitable hair mask or leave-in product if your hair needs additional conditioning
-
Use cool water at the end of your wash if you enjoy how it feels, but do not expect it to accelerate growth
For shinier hair, proper conditioning and reducing damage are more useful strategies than relying on water temperature.
Myth 6: Plucking One Grey Hair Causes More Grey Hairs
The myth: If you pull out one grey hair, several more grey hairs will grow back in its place.
The truth: Plucking one grey hair does not cause neighbouring follicles to suddenly turn grey.
Each hair grows from its own follicle, and the colour of that hair is largely influenced by the pigment-producing cells within that follicle.
However, repeatedly plucking hairs is still not a good habit. Constantly pulling hairs from the same area can injure the follicle and may eventually contribute to local hair loss.
What to Do Instead
-
Trim unwanted grey hairs close to the scalp
-
Consider hair colour or root touch-ups if you want to cover greys
-
Avoid repeatedly plucking individual hairs
-
Remember that greying is a normal part of ageing and is strongly influenced by genetics
One grey hair is not responsible for creating the next one.
Myth 7: Natural or Homemade Hair Masks Are Always Better
The myth: Ingredients from your kitchen must be safer because they are natural and contain fewer chemicals.
The truth: Natural does not automatically mean gentle, effective, or suitable for your scalp.
Ingredients such as lemon juice, baking soda, and concentrated essential oils can irritate the scalp or affect the hair's condition when used incorrectly. Homemade mixtures also do not necessarily have the stability, preservation, or testing that professionally formulated hair products undergo.
What to Do Instead
-
Read the ingredient list, even when a product is marketed as natural or organic
-
Patch test new products when appropriate
-
Avoid applying harsh kitchen ingredients directly to your scalp or hair
-
Choose products formulated specifically for the hair and scalp
-
Stop using a product if it causes burning, itching, or significant irritation
"Natural" is a description of an ingredient's origin—not a guarantee of safety.
Myth 8: Using More Hair Products Gives Better Results
The myth: The more oils, masks, serums, conditioners, and treatments you add, the healthier your hair will become.
The truth: Hair does not necessarily benefit from a complicated routine.
Using too many products can lead to buildup, make hair feel heavy or greasy, and make it harder to identify which product is actually helping—or causing a problem.
A simple routine designed around your hair type and concerns can often be more practical than constantly layering new treatments.
What to Do Instead
-
Identify your main hair concerns first
-
Choose products that address those specific needs
-
Build your routine around shampoo and conditioner
-
Add one or two targeted treatments if necessary
-
Give new products enough time before adding several others
You do not need a 10-step hair routine to have healthy-looking hair. The right products matter more than the number of products you use.
Conclusion: Let Go of Hair Care Myths
Many hair care habits are passed down as unquestionable rules, but your hair does not need every traditional trick to stay healthy.
Trimming does not make your roots grow faster. Washing your hair does not automatically cause hair loss. Brushing it 100 times can create unnecessary friction, overnight oiling is not essential for everyone, and cold water cannot accelerate hair growth.
The better approach is much simpler: understand your scalp, treat your hair gently, choose products that suit your needs, and avoid doing more simply because you have heard that more is better.
This matters when you are building a personal care routine, whether you are looking for the best skincare products for beginners or trying to improve your hair care habits.
Good hair care does not have to be complicated. It starts with knowing what your hair actually needs—and leaving the myths behind.
FAQ
Does trimming hair make it grow faster?
No. Hair growth takes place at the follicles in your scalp, so trimming the ends does not increase the growth rate. Regular trims can reduce split ends and breakage, helping you retain length.
Is washing hair daily bad?
Not necessarily. Washing frequency should depend on your scalp and hair needs. People with oily scalps may need to wash frequently, while those with drier scalps may prefer longer intervals between washes.
Should I brush my hair 100 strokes a day?
No. There is no need to follow the 100-stroke rule. Excessive brushing can create friction and contribute to breakage and split ends. Brush gently and only as much as needed.
Is leaving oil on overnight good for hair?
Not necessarily. Leaving oil on overnight does not guarantee additional benefits and may contribute to buildup or scalp discomfort for some people. A shorter pre-wash application can be sufficient, particularly when the goal is to condition the hair lengths.
Does a cold-water rinse make hair grow faster?
No. Cold water does not stimulate hair growth. It may temporarily change how the hair feels, but growth occurs at the follicles within the scalp.
